The question comes down to does one have the room for full badies. They are great, but are bulky. The shells are more compact. I personally always stake my shells to give them better visability and add the shadow lines as a standing duck would have.
I use G&H shells myself becuase I use FB goose decoys which take up enough room already.
As for location, put the duck decoys upwind of the goose decoys for a great double winning spread.
